FRAMEOPERATOR Frame Operator Usage: o=frameoperator(F, f); Input parameters: F : frame f : input vector Output parameter: h : output vector h=FRAMEOPERATOR(F,f) applies the frame operator associated with the frame F to the input f. If the frame F is a tight frame, then h equals f up to the constant frac{1}{A} where A is the lower frame bound of F. If the frame F* is an orthonormal basis, or more general a Parseval frame, then h equals f.
